Did you know?
In 1896, in the year that Winthrop Leonard was born, in April, the first study on global warming due to CO2 - carbon dioxide - in the atmosphere was published by Swedish scientist Svante Arrhenius. Arrhenius concluded that human activity due to the Industrial Revolution would amplify CO2 in the atmosphere, causing a greenhouse effect. His conclusions have been extensively tested in the ensuing 100+ years and are still seen to hold true.
Did you know?
In 1905, he was merely 9 years old when the German born physicist, Albert Einstein, proposed the Special Theory of Relativity: 1) that observers can never detect uniform motion except relative to other objects and that 2) unlike the velocity of massive objects, the speed of light is a constant and is the same for all observers independent of their constant velocity toward or away from the light source. Not such simple concepts that lead to the equation everyone now knows: E = mc2.
